How to Start the PDP-11/03L
- Make sure the HALT switch is in the DOWN position (CPU Halted).
- Apply power to the peripheral devices and allow sufficient "warm-up" time for the CRT Display.
- Apple power to the central processing unit.
- Move the HALT switch to the UP position (CPU Enabled.)
- Cycle the RESTART switch (the switch is spring loaded -- just briefly press it upwards.)
- The console terminal should display the number 28 (this is the memory capacity detected in K-Words) and then the START? prompt on the next line.
- The following start commands are accepted:
- Y -- This boots from the default device (DY0:)
- N -- This terminates the boot process and enters console ODT with the CPU Halted. For more information on ODT, consult the LSI-11 CPU Reference Manual.
- DY0: -- This boots from drive 0 (the Default option.)
- DY1: -- This boots from drive 1 (remember to mount a system disk in drive 1 -- this is normally only done if there is a failure of drive 0.)
- If you selected anything other than (N), RT-11 should load and display the start message. If the boot process fails, the CPU will halt (the run light will go out) and enter console ODT mode. This usually means a hardware failure of the boot device or corruption of the system disk.
